860-0060-08 uses 870-0040 micrometer as a driving screw. The platform is preloaded against the screw.

860-0060-08 and 860-0060-10 use their own integrated driving screws. The screw has a micrometric scale (on the body and knob). The pitch of the screw is 0.5 mm. Custom pitch and gears are available on request.

The platform of 860-0060-08 (-10) is preloaded by a collar of our original design on the screw, rendering an increased load capacity, stability, and reduced backlash.
